Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

Out of 4843 participants screened, 10 failed screening (6 due to protocol violations, 2 due to investigator decision and another 2 subjects due to technical problems [interactive voice response system did not work properly]). 4833 participants were randomized (2420 to rivaroxaban and 2413 to enoxaparin/VKA).

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

Percentage of Participants With the Composite Variable Comprising Recurrent DVT, Non-fatal PE and All Cause Mortality Until the Intended End of Study Treatment [ Time Frame: 3-, 6-, or 12-month study treatment period ]

The valid-for-safety analysis population consisted of all participants who were randomized with valid informed consent and received at least one dose of anticoagulant study treatment after randomization (i.e. enoxaparin, warfarin, acenocoumarol, rivaroxaban). Participants were analyzed according to the treatment they actually received.
